|I have a crape murdel and will not grow any flowers for the last five years.|
Crape myrtles need lots of sun to bloom well. They also prefer to have a bit of water to keep them vigorous. Some varieties are slower to start blooming than others.
If your plants are in full sun and have not yet bloomed in 5 years I suggest you fertilize them with a cup of 15-5-10 or similar fertilizer in an 8 foot diameter area beneath each plant (4 feet out from the trunk in all directions). Also give them a good soaking once a week. If they used to bloom they may benefit from some pruning this winter to encourage vigorous regrowth.
Thanks for the question. Please stop in again soon!
